Dealing with Loss

I've been struggling these passed several days. A friend of mine passed away the day before Easter and then my best friend's friend passed away about 2 weeks later. She's been struggling terribly, and I've been trying to stay strong and be there for her. The only problem is that I can not do it anymore. I finally broke down and cried. I felt that my friend needed me more, and I had had two weeks to mourn, so I had to be there for my friend. I know it takes longer than 2 weeks to get through the loss of a loved one though. I just hope it won't take me as long as it did for my grandfather. I'll always and forever miss her, but I want it to get easier and not take so long for it to get easier. Everytime I see something in my room that my friend Nancy gave me; I want to break down and cry. For a while, I couldn't do it, but now I can.
